Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Unauthenticated Sensitive Data Exposure in Object Cache 4 everyone <= 2.3.2 versions.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The Object Cache 4 everyone WordPress plugin versions 2.3.2 and below contains an unauthenticated sensitive data exposure vulnerability in its object cache functionality. An attacker can access cached sensitive data without any authentication by directly querying the cache layer.

MitigationUpdate the Object Cache 4 everyone plugin to the latest patched version (likely 2.3.3 or higher) immediately, or remove the plugin if no longer needed.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm plugin installation
    Navigate to WordPress admin dashboard > Plugins, or inspect wp-content/plugins/ directory for a folder containing 'object-cache-4-everyone' or similar naming
    Affected if The Object Cache 4 everyone plugin is present in the plugins directory or listed in WordPress admin
  2. Identify installed version
    Open the main plugin PHP file (usually in wp-content/plugins/object-cache-4-everyone/) and locate the version header in the plugin comment block, or check readme.txt for the 'Stable tag' entry
    Affected if Version number is 2.3.2 or lower
  3. Verify plugin is active
    Check WordPress admin > Plugins > Installed Plugins to see if the plugin is activated, or query the wp_options table for option_name='active_plugins'
    Affected if Plugin is activated and running on the site
  4. Assess exposure level
    Review cache configuration files (wp-config.php cache settings) and any external cache backend configurations (memcached/redis configs if used) to understand what data may be exposed
    Affected if The plugin is active and handles sensitive cached data without requiring authentication for cache queries

User is affected if the Object Cache 4 everyone plugin versions 2.3.2 or below is installed and active on their WordPress site, allowing unauthenticated access to cached sensitive data.
